The Black Death

Cause of the Bubonic Plague

The Bubonic Plague is an infection of the lymphatic system (part of the circulatory system) cause usually from a flea called a Xenopsylla cheopis (the rate flea). Also in extreme cases, the infection can be transmitted through direct contact with the boils that appear on someones skin or through a cough of someone that has the plague.

How it is Transmitted

The bubonic plague is transmitted by 3 man ways. The first main way it i transmitted is from a bit of the rat flea. That is the most common way it is transmitted. When the plague gets extremely infectious, it can get transmitted from touching the sores of from exposer to a cough from someone who has it. If the plague springs up in a highly populated area then there is a huge risk of it spreading like wild fire because t is so infectious.

Effects on Human Population

This plague is extremely infectious. If there was a large outbreak of this plague than there would a lot of deaths. It is a very rapped killer and would kill tons of people. If this plague infects your food supply then we would have a lot more than just human deaths to deal with.


Since the Bubonic Plague is such a fast killer, someone who has it must go to treatment within 24 hours of the first symptoms occurring in order to have a good chance of survival. But if a person gets to the hospital in time there are a couple of treatments to try. The first option is to try antibiotics such as Gentamycin or Streptomycin. the second is to use two other antibiotics called Tetracyclines and Chloramphenicol. There really is no way to prevent from it but you need treatment quickly if you do get it to stand a chance to survive.

Break outs

The most common place for this plague to surface is in Africa. One statistic is that between 1000 to 2000 cases are reported to the Word Health Organization every year. The World Heath Organization also says there is a 8-10 percent mortality rate from the break outs.
